Synchronizing sleeve 18 is formed as cylindric.The periphery of synchronizing sleeve 18 is provided with the engagement portion 38 can closed with the illustrated fork of omission.
Lock ring 24 is formed as cylindric.The end (end in the left side of Fig. 1 and Fig. 2) of the axial side of the outer circumferential face of lock ring 24 is formed with protuberance 42, and the recess 37 of this protuberance 42 and synchronous hub 16 is with can the relative mode rotated chimeric (engaging) within the limits prescribed.The outer circumferential face frictional engagement of the synchronous cone 15 that the inner peripheral surface of lock ring 24 can rotate integrally with same speed change gear 14.
In the present embodiment, by the range set of regulation be the half pitch (half from the center of dental inlay tooth 22 to the distance at the center of adjacent dental inlay tooth 22) of dental inlay tooth 22.Thus, lock ring 24 can relative to the half pitch of the relative rotating gripper inserted tooth 22 of synchronous hub 16.
Synchronisation spring 26 is formed as ring-type.Synchronisation spring 26 moves to speed change gear 14 side in the axial direction along with synchronizing sleeve 18, and pushes lock ring 24 to synchronous cone 15.
Be configured with one piece of sheet metal stamping-out annulus 52 formed circlewise at the end face (end face on the right side of Fig. 1 and Fig. 2) of the axial opposite side of the peripheral part 16a of synchronous hub 16.Annulus 52 is provided with the U-shaped otch 54a being cut into roughly U-shaped in the mode corresponding with recess 37.Further, the tongue piece 54 of being delimited by U-shaped otch 54a is bent into right angle towards recess 37 (direction towards leaving protuberance 42).The circumferential both side edges of tongue piece 54 abuts with the circumferential bi-side of recess 37.By the Qian He between this tongue piece 54 and recess 37, synchronous hub 16 and annulus 52 rotate integratedly, and both become the state that can not relatively rotate.
Further, as shown in Figure 4 A and 4 B shown in FIG., annulus 52 is formed with linear incision 50a, this linear incision 50a is cut into outer rim from a bight 2 bights of U-shaped otch 54a towards radial outside.It is L-shaped that the part of the outer periphery by this linear incision 50a, U-shaped otch 54a and annulus 52 being delimited is bent into cross section from central authorities towards the protuberance 42 of lock ring 24, thus forms the plate spring part 50 of the 1st mode of execution.
The protuberance 42 being arranged at lock ring 24 is provided with accommodation section 44, and the terminal part of plate spring part 50 can be accommodated in this accommodation section 44.Accommodation section 44 is made up of the groove of V shape, and is configured to before protuberance 42 contacts with recess 37, and plate spring part 50 contacts with accommodation section 44.In other words, when plate spring part 50 contacts with accommodation section 44, plate spring part 50 and accommodation section 44 are configured to protuberance 42 and separate in the circumferential with recess 37 and have gap.
3 plate spring part 50, for having the elastomer of spring, such as, are formed by stainless steel.The terminal part of plate spring part 50 is made up of the free end that can freely swing.The maximum variation of rotating speed when being in idling mode according to vehicle and when vehicle travels, driving source and the moment of inertia of lock ring 24 and obtain maximum rotational energy, be set as required elastic force according to calculated maximum rotational energy by plate spring part 50.
Further, as the manufacture method of plate spring part 50, annulus 52 and tongue piece 54, first, by one piece of sheet metal stamping-out circlewise, the parts of the ring-type gone out at stamping-out form U-shaped otch 54a and linear incision 50a.Then, as shown in Figure 4 B, by bending tongue piece 54 and plate spring part 50, the plate spring part 50 be connected with annulus 52 can easily be manufactured.
Then, the action of the synchromesh gear 10 of speed changer is described.State synchronizing sleeve 18 being positioned at the central authorities of synchronous hub 16 is defined as neutral state.
First, about synchromesh gear 10, when synchronizing sleeve 18 starts mobile from neutral state to speed change gear 14 side, the spline tooth 20 of synchronizing sleeve 18 presses synchronisation spring 26, thus produces between synchronous cone 15 and lock ring 24 and rub.Further, the spline tooth 20 of synchronizing sleeve 18 contacts with the dental inlay tooth 22 of lock ring 24.
Further, when lock ring 24 is synchronous with the rotation of synchronous cone 15, by synchronizing sleeve 18 will to the power of speed change gear 14 side movement, the mode that lock ring 24 to enter with the spline tooth 20 of synchronizing sleeve 18 between the adjacent dental inlay tooth 22 of lock ring 24 relative to synchronizing sleeve 18 rotates.Further, the spline tooth 20 of synchronizing sleeve 18 push lock ring 24 aside dental inlay tooth 22 between and move to speed change gear 14 side.
Further, the dental inlay tooth 12 of the spline tooth 20 and speed change gear 14 of having pushed the synchronizing sleeve 18 between dental inlay tooth 22 aside contacts.Further, the spline tooth 20 of synchronizing sleeve 18 is also pushed the dental inlay tooth 12 of speed change gear 14 aside and engages with the dental inlay tooth 12 of speed change gear 14.
According to the synchromesh gear 10 of the 1st mode of execution, do not have to form buffer part by making the corresponding part of key spring bend to rectangular-shaped as in the past.Further, the end of plate spring part 50 is the free ends that can freely swing.Thus, in the synchromesh gear 10 of the 1st mode of execution, plate spring part 50 more easily swings than ever, can improve the shock-absorbing capacity of plate spring part 50, thus can improve the rejection to the bruit de froissement between protuberance 42 and recess 37 than ever further.
Further, due to accommodation section 44 is formed as V shape, therefore, protuberance 42 is more close to the sidewall (with reference to Fig. 5 B) of recess 37, and the power acting on the axial vane surface side towards protuberance 42 of plate spring part 50 from the plane of inclination of the accommodation section 44 of V shape is stronger.Therefore, protuberance 42 is more close to the sidewall of recess 37, and the frictional force between lock ring 24 and synchronous cone 15 more increases.Therefore, protuberance 42 collides with the sidewall of recess 37 more lentamente, can improve the rejection to bruit de froissement further.
Further, when lock ring 24 is synchronous with the rotational speed of synchronous cone 15, move to speed change gear 14 side between the dental inlay tooth 22 that the spline tooth 20 of synchronizing sleeve 18 pushes lock ring 24 aside.Now, as shown in Figure 5 C, by means of the recuperability of plate spring part 50, the protuberance 42 of lock ring 24 will to the central mobile of the recess 37 of synchronizing sleeve 18.Thus, requiredly when the spline tooth 20 reducing synchronizing sleeve 18 is between the dental inlay tooth 22 pushing lock ring 24 aside a point load is dialled.
Further, in synchromesh gear in the past, also exist as lower device: the friction means slid freely is set in the side of synchronous hub, between protuberance and recess, realizes buffer function by surface friction drag.But, synchromesh gear according to the present embodiment, owing to not using frictional force, therefore, it is possible to prevent the spline tooth 20 of synchronizing sleeve 18, between the dental inlay tooth 22 pushing lock ring 24 aside time required increase of dialling point load, thus the spline tooth 20 of synchronizing sleeve 18 is engaged smoothly with the dental inlay tooth 12 of speed change gear 14.
In addition, in the synchromesh gear 10 of the 1st mode of execution, be formed on synchronous hub 16 to by recess 37, the situation that protuberance 42 is formed on lock ring 24 is illustrated.But recess of the present invention and protuberance are not limited thereto.Such as, the situation about being formed on synchronous hub on lock ring, by protuberance that is formed in by recess also can apply the present invention, can obtain its effect.
(the 2nd mode of execution)
Then, with reference to Fig. 6 A to Fig. 7 C, the synchromesh gear 10 of the 2nd mode of execution of the present invention is described.Fig. 6 A is by the partial sectional view shown in a part for synchronous hub 16 amplification.
The synchromesh gear 10 of the 2nd mode of execution except do not have annulus, plate spring part 50 different from the shape of accommodation section 44 except, other are all identical structure with the 1st mode of execution, mark identical label and the description thereof will be omitted.
About the recess 37 of the 2nd mode of execution, it is T-shaped that the union body 34 being positioned at its radially inner side is formed as cross section.The cardinal extremity of the plate spring part 50 of the 2nd mode of execution is provided with the fixing part 56 that cross section is C-shaped, and this fixing part 56 is fixed in union body 34 in the mode of the outer rim of surrounding the union body 34 that cross section is T-shaped.
As shown in Figure 6B, about the plate spring part 50 of the 2nd mode of execution, turn 90 degrees by turning round at its base end part and constitute the board plane vertical relative to the board plane of fixing part 56.In addition, the formation method of the plate spring part 50 of the 2nd mode of execution is not limited thereto.Such as, bending the part that also can be configured to be the side of the union body 34 of T-shaped from the covering cross section in fixing part 56.
Accommodation section 44 is made up of the groove of U-shaped.The bi-side of the circumference of the accommodation section 44 abutted with the terminal part of plate spring part 50 are plane of inclination.Thus, in the synchromesh gear 10 of the 2nd mode of execution, the accommodation section 44 of the 1st mode of execution formed with by V shape groove is the same, be also protuberance 42 more close to the sidewall of recess 37, the frictional force between lock ring 24 and synchronous cone 15 more increases.Therefore, protuberance 42 collides with the sidewall of recess 37 more lentamente, can improve the rejection to bruit de froissement further.
(other mode of execution)
In addition, although the rejection improved further bruit de froissement cannot be expected, but as shown in Fig. 8 A to Fig. 8 C, even if be made up of the circumferential bi-side of the accommodation section 44 be made up of U-shaped groove the face parallel with the axial direction of running shaft X, when plate spring part 50 contacts with accommodation section 44, as long as plate spring part 50 and accommodation section 44 are configured to protuberance 42 with recess 37 in the circumferential across gap, the action effect of the present invention of the suppression that just can obtaining crashes hits sound.
And, in the synchromesh gear 10 of the 1st and the 2nd mode of execution, use as lower device is illustrated: synchronizing sleeve 18 presses lock ring 24 via synchronisation spring 26, the frictional force between lock ring 24 and synchronous cone 15 is increased, makes synchronous hub 16 synchronous with the rotation of speed change gear 14.But synchromesh gear of the present invention is not limited thereto.
Such as, as shown in the reference example of Fig. 9, in the synchromesh gear of keyed with the synchronous key 86 being pressed on synchronizing sleeve 18 by spring 80, also can apply plate spring part of the present invention and accommodation section.In this case, as long as carry out suitable design alteration in the mode that can configure plate spring part 50 of the present invention to recess 37.
